Yes, but, then it's this oddball accessory that you must keep around, and labeled, and still end up just losing after a while, and your grandnephew never knows what it's for a few years later in a box of mystery parts. Or you could just stuff a piece of paper right in the cavity near the main rom

Re: [M100] Figtronix Main ROM adapter

Hi Brian, Thanks for the detailed explanation. Totally makes sense. My M100s are indeed all the old style PCB that use the non-standard LH* chip. I do wish I was one of those lucky folks with the later model PCBs. One of the reasons I created the Worldwide Model T Registry database on

Re: [M100] Figtronix Main ROM adapter

...You could make a board where the chip is soldered on, and that would fit in the original socket. The problem then is, that chip would not be re-programmable very easily, because the combined chip-on-adapter creates a non-standard pinout that a programmer doesn't support... A pgming adapter

Did you open the write-protect tab on the disk? I have observed that it ignores an officially copied disk (made on a 720K disk using the backup utility), if the write-protect hole is closed. On Aug 23, 2017 4:05 PM, "Kurt McCullum" wrote: > A bit too soon to declare

Re: [M100] Figtronix Main ROM adapter

The problem is that the new adapter is too tall for the available space, if it's plugged in to the original socket. The reason it's too tall is because of the plcc socket. Through-hole style plcc sockets are pretty tall. The way that adapter works, you lose the ability to plug the original rom

Re: [M100] TPDD Client Link

Ah, that's a bummer then. How was the M100 version (and T200 version for that matter) ever distributed? Was it shipped on cassette, or did they release it on a TPDD/TPDD2 disk? On Wed, Aug 23, 2017 at 3:53 PM, Kurt McCullum wrote: > Yes it does, unfortunately. The

Re: [M100] TPDD Client Link

Yes it does, unfortunately. The dictionary disk works with the ROM and RAM versions of Sardine. The UR-II has a loader that will load the RAM version of Sardine into memory. That program will then access the Dictionary disk. But, the only RAM version that has been found is for the T200.

Re: [M100] Utility disk image from sector access

Yes, you can create your own Utility disk with this. I’ll do some kind of a writeup but the utility is pretty easy to use. The cable is a standard 9 to 25 modem cable (Not NULL modem) attached to a female to female adapter and then attached to the TPDD2. I uploaded an image of the

I have it. I posted it quite some time ago and you can find it I the members area. Steve Adolph sent me the image after he wrote a utility to extract it from a TPDD1. I use it with both versions of mComm. I will try to write it to a TPDD2 disk but I’m not sure what the results will be. Kurt

Re: [M100] Utility disk image from sector access

Figured it out. There is indeed an ID field for every track. This is read by backup.ba before the track data is read. Then on the write portion of backup.ba, it is written back to the track before the data is laid down. The end result is a perfect copy that boots just as the original Utility

A bit too soon to declare total success. I can duplicate data disks without any issues. I can even duplicate the Utility disk. But even though the duplicate has all the same data, it won’t auto boot. So those extra save commands that I think play with the ID portion of the track are essential

I’ll document what I’ve got John. The backup utility that uses floppy does some strange calls which I don’t understand at all. But, if one reads the tracks from 0 to 80 and then in turn writes them from 0 to 80, those calls are not needed. Backup does some extra reads to determine just how
